By 2050, urban centers will be built synchronously with complete water drainage systems, so that urban flooding will come to an end and all residential wastewater will be treated up to standards before being discharged into receiving waters.
This target is set in Prime Minister Decision No. 589/QD-TTg of April 6, approving the revised orientations for water drainage in urban centers and industrial parks up to 2025, with a vision toward 2050.

The new decision is intended to improve the relevant mechanisms and policies so as to develop stable and synchronous water drainage systems through building networks of wastewater collection, transmission and treatment facilities, operating wastewater treatment plants at full capacity, increasing connections to sewers by households, and conducting regular maintenance of water drainage systems.
According to the decision, by 2020, the service capacity of urban water drainage system will be expanded to over 70 percent. All urban roads and residential streets will have rainwater drainage systems installed.
By 2025, 50 percent of wastewater from urban centers of grade II upward and 20 percent of wastewater from urban centers of grade V upward will be collected and treated up to standards, while the service capacity of urban water drainage system will be expanded to over 80 percent.
In order to achieve the said targets, water drainage master plans will be revised so as to adapt to climate change. Urban flooding maps will be drawn based on various climate change scenarios. Meanwhile, maps of areas prone to flooding, landslides and flashfloods will be made for all provinces and centrally run cities as well as coastal and mountainous areas.
Capital will be poured into projects to build centralized water drainage systems in big urban centers and river basins. The State will prioritize projects to tackle serious environmental pollution in residential areas while encouraging localities to support craft villages and production and business establishments in building water drainage systems.- (VLLF)
